BACKGROUND OF THE INVENTION

Light bars or emergency lights of the type used on emergency vehiclessuch as fire trucks, police cars, and ambulances, utilize warning signallights to produce a variety of light signals. These light signalsinvolve the use of various colors and patterns. Generally, these warningsignal lights consist of incandescent and halogen light sources havingreflective back support members and colored filters.

Many problems exist with the known methods for producing warning lightsignals. One particular problem with known light sources is theirreliance on mechanical components to revolve or oscillate the lamps toproduce the desired light signal. Additionally, these componentsincrease the size of the light bar or emergency lights which mayadversely affect the vehicles aerodynamic characteristics. Moreover,there is an increased likelihood that a breakdown of the light bar orlight source will occur requiring the repair or replacement of thedefective component. Finally, the known light bars and light sourcesrequire a relatively large amount of electrical current duringoperation. The demands upon the electrical power system for a vehiclemay therefore exceed available electrical resources reducingoptimization of performance.

Halogen lamps or gaseous discharge xenon lamps generally emanate largeamounts of heat which is difficult to dissipate from a sealed lightenclosure or emergency light and which may damage the electroniccircuitry contained therein. In addition, these lamps consume largeamounts of current requiring a large power supply or battery orelectrical source which may be especially problematic for use with avehicle. These lamps also generate substantial electromagnetic emissionswhich may interfere with radio communications for a vehicle. Finally,these lamps, which are not rugged, have relatively short life cyclesnecessitating frequent replacement.

Another problem with the known warning signal lights is the use offilters to produce a desired color. Filtering techniques produce moreheat that must be dissipated. Moreover, changing the color of a lightsource requires the physical removal of the filter from the light sourceor emergency light and the replacement of a new filter. Furthermore,filters fade or flake over time rendering the filters unable toconsistently produce a desired color for observation in an emergencysituation.

These problems associated with traditional signaling lamps areexacerbated by the fact that creating multiple light signals requiresmultiple signaling lamps. Further, there is little flexibility inmodifying the light signal created by a lamp. For example, changing astationary lamp into one that rotates or oscillates would require asubstantial modification to the light bar which may not be physically oreconomically possible.

The present invention generally relates to electrical lamps and to highbrightness light-emitting diode or “LED” technology which operates toreplace gaseous discharge or incandescent lamps as used with vehiclewarning signal light sources.

In the past, illumination lamps for automobile turn signals, brakelights, back-up lights, and/or marker lights/headlights frequently haveaccompanying utility parabolic lens/reflector enclosures which have beenused for utility warning signals or emergency vehicle traffic signaling.These signaling devices as known are commonly referred to as “unmarkedcorner tubes,” or “dome tubes. A problem with these illumination lampsis the cost and failure rate of the known “unmarked corner tubes,” or“dome lights.” The failure rate of these devices frequently results in asignificant amount of “down time” for a vehicle to effectuatereplacement. Further, an officer is frequently unaware that a vehiclelight is inoperative requiring replacement. This condition reduces thesafety to an officer during the performance of his or her duties. Inaddition, the reduced life cycle and failure rate of the knownillumination devices significantly increases operational costsassociated with material replacement and labor. A need, therefore,exists to enhance the durability, and to reduce the failure rate, ofillumination devices used with vehicles while simultaneously reducingthe cost of a replacement illumination source.

In the past, the xenon gaseous discharge lamps have utilized a sealedcompartment, usually a gas tube, which may have been filled with aparticular gas known to have good illuminating characteristics. One suchgas used for this purpose was xenon gas, which provides illuminationwhen it becomes ionized by the appropriate voltage application. Xenongas discharge lamps are used in the automotive industry to provide highintensity lighting and are used on emergency vehicles to provide avisible emergency signal light.

A xenon gas discharge lamp usually comprises a gas-filled tube which hasan anode element at one end and a cathode element at the other end, withboth ends of the tube being sealed. The anode and cathode elements eachhave an electrical conductor attached, which passes through the sealedgas end of the lamp exterior. An ionizing trigger wire is typicallywound in a helical manner about the exterior of the glass tube, and thiswire is connected to a high voltage power source typically on the orderof 10-12 kilowatts (kw). The anode and cathode connections are connectedto a lower level voltage source which is sufficient to maintainillumination of the lamp once the interior gas has been ionized by thehigh voltage source. The gas remains ignited until the anode/cathodevoltage is removed; and once the gas ionization is stopped, the lamp maybe ignited again by reapplying the anode/cathode voltage and reapplyingthe high-voltage to the trigger wire via a voltage pulse.

Xenon gas lamps are frequently made from glass tubes which are formedinto semicircular loops to increase the relative light intensity fromthe lamp while maintaining a relatively small form factor. These lampsgenerate extremely high heat intensity, and therefore, requirepositioning of the lamps so as to not cause heat buildup in nearbycomponents. The glass tube of a xenon lamp is usually mounted on alight-based pedestal which is sized to fit into an opening in the lightfixture and to hold the heat generating tube surface in a light fixturecompartment which is separated from other interior compartment surfacesor components. In a vehicle application, the light and base pedestal aretypically sized to fit through an opening in the light fixture which isabout 1 inch in diameter. The light fixture component may have a glassor plastic cover made from colored material so as to produce a coloredlighting effect when the lamp is ignited. Xenon gas discharge lampsnaturally produce white light, which may be modified to produce acolored light, of lesser intensity, by placing the xenon lamp in afixture having a colored lens. The glass tube of the xenon lamp may alsobe painted or otherwise colored to produce a similar result, althoughthe light illumination from the tube tends to dominate the coloring; andthe light may actually have a colored tint appearance rather than asolid colored light. The color blue is particularly hard to produce inthis manner.

Because a preferred use of xenon lamps is in connection with emergencyvehicles, it is particularly important that the lamp be capable ofproducing intense coloring associated with emergency vehicles, i.e.,red, blue, amber, green, and clear.

When xenon lamps are mounted in vehicles, some care must be taken toreduce the corroding effects of water and various chemicals, includingroad salt, which might contaminate the light fixture. Corrosive effectsmay destroy the trigger wire and the wire contacts leading to the anodeand cathode. Corrosion is enhanced because of the high heat generatingcharacteristics of the lamp which may heat the air inside the lampfixture when the lamp is in use, and this heated air may condense whenthe lamp is off resulting in moisture buildup inside the fixture. Thebuildup of moisture may result in the shorting out of the electricalwires and degrade the performance of the emission wire, sometimespreventing proper ionization of the gas within the xenon gas dischargelamp.

Warning lights, due to the type of light source utilized, may berelatively large in size which in turn may have an adverse affect uponadjacent operational components. In addition, there is an increasedlikelihood for a breakdown of the light source requiring repair orreplacement of components.

Another problem with the known warning signal lights is the use ofrotational and/or oscillating mechanisms which are utilized to impart arotational or oscillating movement to a light source for observationduring emergency situations. These mechanical devices are frequentlycumbersome and difficult to incorporate and couple onto variouslocations about a vehicle due to the size of the device. Thesemechanical devices also frequently require a relatively large powersource to impart rotational and/or oscillating movement for a lightsource.

Another problem with the known warning signal lights is the absence offlexibility for the provision of variable intensity for the lightsources to increase the number of available distinct and independentvisual light effects. In certain situations it may be desirable toprovide variable intensity for a light signal, or a modulated intensityfor a light signal, to provide a unique light effect to facilitateobservation by an individual. In addition, the provision of a variableor modulated intensity for a light signal may further enhance theability to provide a unique desired light effect for observation by anindividual.

No warning lights are known which are flexible and which utilize avariable light intensity to modify a standard lighting effect. Thewarning lights as known are generally limited to a flashing lightsignal. Alternatively, other warning signal lights may provide asequential illumination of light sources. No warning or utility lightsignals are known which simultaneously provide for modulated and/orvariable power intensity for a known type of light signal to create aunique and desirable type of lighting effect.

No warning signal lights are known which provide irregular or randomlight intensity to a warning signal light to provide a desired lightingeffect. Also, no warning light signals are known which provide a regularpattern of variable or modulated light intensity for a warning signallight to provide a desired type of lighting effect. It has also not beenknown to provide a warning light signal which combines either irregularvariable light intensity or regular modulated light intensity to providea unique and desired combination lighting effect.

It has also not been known to provide alternative colored LED lightsources which may be electrically controlled for the provision of anydesired pattern of light signal such as flashing, pulsating,oscillating, modulating, rotational, alternating, strobe, and/orcombination light effects. In this regard, a need exists to provide aspatially and electrically efficient LED light source for use on anemergency or utility vehicle which provides the appearance of rotation,or other types of light signals.

In view of the above, there is a need for a warning signal light that:

(1) Is capable of producing multiple light signals;

(2) Produces the appearance of a revolving or oscillating light signalwithout relying upon mechanical components;

(3) Generates little heat;

(4) Uses substantially less electrical current;

(5) Produces significantly reduced amounts of electromagnetic emissions;

(6) Is rugged and has a long life cycle;

(7) Produces a truer light output color without the use of filters;

(8) Is positionable at a variety of locations about an emergencyvehicle; and

(9) Provides variable power intensity to the light source withoutadversely affecting the vehicle operator's ability to observe objectswhile seated within the interior of the vehicle.

Other problems associated with the known warning signal lights relate tothe restricted positioning of the signal light on a vehicle due to thesize and shape of the light source. In the past, light sources due tothe relatively large size of light bars or light sources, were requiredto be placed on the roof of a vehicle or at a location which did notinterfere with, or obstruct, an operator's ability to visualize objectswhile seated in the interior of the vehicle. Light bars or light sourcesgenerally extended perpendicular to the longitudinal axis of a vehicleand were therefore more difficult to observe from the sides by anindividual.

The ease of visualization of an emergency vehicle is a primary concernto emergency personnel regardless of the location of the observer. Inthe past, optimal observation of emergency lights has occurred when anindividual was either directly in front of, or behind, an emergencyvehicle. Observation from the sides, or at an acute angle relative tothe sides, frequently resulted in reduced observation of emergencylights during an emergency situation. A need therefore exists to improvethe observation of emergency lights for a vehicle regardless of thelocation of the observer. A need also exists to improve the flexibilityof placement of emergency lights upon a vehicle for observation byindividuals during emergency situations.

A need exists to reduce the size of light sources on an emergencyvehicle and to improve the efficiency of the light sources particularlywith respect to current draw and reduced aerodynamic drag. In addition,the flexibility of positioning of light sources about a vehicle forobservation by individuals is required to be enhanced to optimizeutility for a warning signal light. In order to satisfy these and otherneeds, more spatially efficient light sources such as LED's arerequired. It is also necessary to provide alternative colored LED lightsources which may be electrically controlled for the provision of anydesired pattern of light signal such as flashing, alternating,pulsating, oscillating, variable, modulating, rotational, and/or strobelight effects without the necessity of spatially inefficient and bulkymechanical devices.

In the past, illumination of an area to the front or to the sides of anemergency vehicle during low light conditions has been problematic.Take-down lights have been utilized by law enforcement personnel for anumber of purposes including, but not necessarily limited to, enhancingobservation of an individual in a vehicle on a roadway subject toinvestigation and to hide the location of an officer, or to block ordeter observation of an officer by individuals during law enforcementactivities.

The take-down lights as known have generally been formed of halogen orgaseous discharge xenon lamp illumination sources which have arelatively short useful life, are bulky, have relatively large currentdraw requirements, and which require frequent replacement. A need existsfor a take-down light which has significant illuminationcharacteristics, is spatially efficient, has a long useful life, and hasreduced current draw requirements for use on a law enforcement vehicleor as used as a utility light source.

The alley lights as known also suffer from the deficiencies asidentified for the take-down lights during dark illumination conditions.Alley lights are used to illuminate areas adjacent to the sides of avehicle.

In the past, the intersection clearing lights have been predominatelyformed of halogen, incandescent, and/or gaseous discharge xenonillumination sources. The drawbacks associated with these types ofillumination sources are the relatively high current draw, reduceduseful life and durability necessitating frequent replacement, large RFelectromagnetic emissions which increase radio interference and otherdraw backs as previously discussed. A need therefore exists for anintersection clearing light which solves these and other identifiedproblems and which further has significant illumination characteristics,is spatially efficient, has a long useful life, and has reduced currentdraw requirements for use on a vehicle or as a utility light source.

A problem has also existed with respect to the use of emergency lightson unmarked law enforcement vehicles. In the past, emergency lights forunmarked law enforcement vehicles have consisted of dome devices whichare formed of revolving mechanisms. These lights are usually withdrawnfrom a storage position under a motor vehicle seat for placement upondashboard of a law enforcement vehicle. In undercover situations it hasbeen relatively easy to identify dashboard affixation mechanisms used tosecure these types of dome illumination devices to a dashboard. Theknown dome devices are also clumsy, have large current drawrequirements, and are difficult to store in a convenient location forretrieval in an emergency situation by an individual. A need thereforeexists for an emergency vehicle or utility warning light which isspatially efficient, easily hidden from view, and is transportable by anindividual for retrieval during an emergency situation.

A need also exists for a new emergency vehicle light bar which isaerodynamic and which provides for both a longitudinal illuminationelement and an elevated pod illumination device. A need exists for alight bar having enhanced illumination properties and flexibility forprovision of new and additional warning light signals including, but notlimited to, strobe, variable, modulated, alternating, pulsating,rotational, oscillating, flashing, and/or sequential light signals foruse within an emergency situation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A warning signal light according to the principles of the invention isindicated generally herein as numeral 10. FIGS. 1 and 2 depict light bar70 mounted to an emergency vehicle 104. Light bar 70 includes base 72,mounting means 74, cover 82, and warning signal lights 10. Also includedin light bar 70 are gyrators 90 used to impart motion to warning signallights 10.

Referring to FIGS. 3 and 9, warning signal light 10 comprises lightsupport 12, light sources 30, controller 50 (shown in FIG. 11), andconnecting portion 40 for attaching the warning signal light 10 to lightbar 70 or gyrator 90. The warning signal light 10 operates to create awarning signal for use by an emergency vehicle 104 by selectivelyactivating light sources 30 using controller 50. Alternatively, warningsignal light 10 may be formed of a solitary LED light source 30 at thediscretion of an individual.

Light sources 30 are preferably light emitting diodes (LED's) and aregenerally arranged in aligned columns 32 and rows 34 as shown in FIGS. 7and 9. Each of the light emitting diodes (LED's) may have shoulderportion 38 adjacent LED support 12 and dome 36. LED's 30 are situated tobe in electric communication with controller 50 and a power supply, abattery, or power source. The use of light emitting diodes (LED's) toreplace traditional halogen, incandescent, or gaseous discharge xenonlamps reduces heat generation, current draw, and electromagneticemissions, while increasing lamp life and producing a more true outputlight color.

The controller 50 is used to selectively activate columns 32, rows 34,or individual LED's 30, to illuminate any number of a plurality ofvisually distinct types of warning light signals at any moment; toilluminate more than one of a plurality of visually distinct types ofwarning light signals simultaneously at any moment; to illuminate one ofa plurality of combinations or patterns of visually distinct warninglight signals at any moment, or over any desired period of time, or toilluminate more than one of a plurality of combinations or patterns ofvisually distinct warning light signals over any desired period of time.The plurality of visually distinct warning light signals may include,but are not necessarily limited to, a strobe light signal, a pulsatinglight signal, an alternating light, a modulated light signal, a flashinglight signal, the illusion of a rotating or an oscillating light signal,a reverse character message, or images such as arrows. It should benoted that the controller 50 may also incorporate into any selectedwarning light signal variable or modulated power intensity to facilitatethe provision of a desired unique lighting effect. For example, thecontroller 50 may illuminate one or more LED light sources 30 toestablish a single warning light signal at a given moment.Alternatively, the controller 50 may illuminate one or more lightemitting diode light sources 30 to provide two or more warning lightsignals at any given moment. Further, the controller 50 maysimultaneously, consecutively, or alternatively , illuminate one or moreLED light sources 30 to establish any desired combination or pattern ofilluminated visually distinct warning light signals at any given momentor over a desired period of time. The combination and/or pattern ofvisually distinct warning light signals may be random or may be cycledas desired by an individual. The illumination of one or more patterns orcombinations of warning light signals facilitates the continuedobservation by an individual. Occasionally, the concentration orattention of an individual is diminished when exposed to a repetitive orto a monotonous light signal. The desired purpose for illumination of awarning light signal is thereby reduced. The provision of a pattern,combination, and/or random illumination of visually distinct warninglight signals maximizes the concentration or attention to be receivedfrom an individual observing a warning light signal. The purpose of thewarning light signal is thereby promoted.

FIGS. 11A, 11B, and 11C show an embodiment of controller 50 capable ofselectively activating columns 32, rows 34 or individual LED's 30.Controller 50 generally comprises microprocessor 52 and circuitry 53 andis preferably contained within, attached to, or an element of, LEDsupport 12. It is envisioned that controller 50 may be programmed by anexternal controller 55 and powered through cable R.

In one embodiment, controller 50 generally comprises circuit board 54 orLED mounting surface having microprocessor 52 attached to a low voltagepower supply, battery, or electrical source 56. Microprocessor 52 isconfigured through circuitry 53 to selectively activate columns 32 ofLED's 30. Transistors Q9 and Q10 are in electronic communication withmicroprocessor 52, power supply, battery, or electrical source 56, andtheir respective columns 32.9 and 32.10 of LED's 30. Columns 32 of LED's30 are connected to transistors Q1-Q8, which are in turn connected tomicroprocessor 52 through resistors R1-R8. Microprocessor 52 is capableof selectively activating transistors Q1-Q8 to allow current flowingthrough transistors Q9 and Q-10 to activate the selected column 32 ofLED's 30. This circuit is capable of producing a strobe light signal, analternating light signal, a modulated signal, a revolving light signal,a pulsating light signal, an oscillating light signal, or flashing lightsignal, a reverse character message, or images such as arrows.

In one embodiment, a rotating or oscillating light signal may beestablished by the sequential illumination of entire columns 32 of LED's30 by turning a desired number of columns on and then sequentiallyilluminating one additional column 32 while turning another column 32off. Alternatively, the rotating or oscillating warning light signal maybe created by selectively activating columns 32 of LED's 30. Thefollowing algorithm may be used to provide a counterclockwise revolvinglight signal (FIG. 9):

A clockwise revolving light signal may be created by performing steps1-19 in descending order then repeating the steps. An oscillating lightsignal may be created by performing: (a) steps 7 through 16 in ascendingorder; (b) steps 7 through 16 in descending order; and (c) repeating (a)and (b).

A second embodiment of controller 50 provides a means for activatingLED's 30 individually to allow for greater flexibility in the type ofwarning light signal created. This embodiment of the invention iscapable of displaying information in different colors or patterns.Depending on the size of the display, it may be necessary to scroll thesymbols or characters across the display to accommodate for a largervisual appearance. It is envisioned that the mirror image of patterns,symbols, or characters could be displayed making the message easilyreadable by drivers viewing the signal in a rear view mirror. It is alsoenvisioned that this embodiment of the invention could display arrowsindicating a direction a vehicle is to travel or other images as shownin FIG. 2. In addition, combinations of warning signal lights, directionarrows, and other information carrying signals or images, could bedisplayed simultaneously by the invention.

LED support 12 is envisioned to have several embodiments. Oneembodiment, shown in FIG. 9, consists of a panel 14 having front 16,back 18, top 20, bottom 22 and sides 24. LED's 30 are arranged on front16, with domes 36 extending therefrom, in columns 32 and rows 34. LED's30 are in electric communication with controller 50 which may becontained or sealed within LED support 12 to provide protection from theelements.

Another embodiment of warning signal light 10 is depicted in FIG. 10.Here, the backs 18 of two panels 14 are attached together to allow for alight signal to be produced on two sides. The two panels 14 form LEDsupport 12. Alternatively, it is envisioned that a single panel 14having LED's arranged about front 16 and back 18 could be used as well.

FIGS. 6 and 8 show further embodiments of warning signal light 10. InFIG. 8, panels 14 are used to form an LED support 12 having four sidesand generally shaped as squared. FIG. 6 shows panels 14 connected toform an LED support 12 having three sides and generally triangular inshape. In both embodiments, LED's 30 are arranged about the fronts 16 ofthe panels 14. It is further envisioned that panels 14 may be integralto each other.

Yet another embodiment of warning signal light 10, consists of aflexible panel 14 and controller 50 to allow LED support 12 to be formedinto various shapes. FIG. 5 shows LED support 12 formed into a cylinder.Further variations include the use of flexible panels 14 to form othershapes such as semicircles (FIG. 12) or to simply conform to a surfaceof an emergency vehicle (FIGS. 13 and 14). This embodiment isparticularly useful for undercover vehicles which generally position thewarning signal lights inside the vehicle. For example, panel 14 could beattached to the front, rear, or side window of an undercover policevehicle.

It should be noted that numerous other shapes could be formed frompanels 14 including those formed from combinations of flat, curved, andflexible panels at the preference of an individual.

In each of the embodiments discussed above, the array of LED's 30 may beformed of the same or differently colored LED's. Generally, each column32 or row 34 may consist of a series of differently colored LED's.Controller 50 may be configured to select the color of the LED's to beilluminated forming the light signal. Accordingly, the user may select ablue, red, white, yellow, green, or amber color or any combinationthereof to be used as the color of light signal. Alternatively, thewarning signal 10 may be formed of individual LED's 30 which may beselectively illuminated at the discretion of an individual.

It is also envisioned that the controller 50 may control warning signallights 10 having multiple sides (FIGS. 5, 6, 8, and 10) such that eachside is capable of producing warning light signals or combinationwarning light signals that are independent and/or different from thoseproduced upon the other sides. For example, the squared shape warningsignal light shown in FIG. 8 may produce or simulate a red revolvinglight on first side 15.1, while second side 15.2 is simultaneouslyproducing a blue oscillating light, while third side 15.3 is producingor simulating a stationary white light, and while fourth side 15.4 isproducing a white strobe light.

Another embodiment of warning signal light 10 is depicted in FIGS. 1 and2 as light bar 70 which extends from driver side 100 to passenger side102 of emergency vehicle 104. Cover 82 protects light bar 70 from theelements. Each side of light bar 70 may have LED's 30 to produce orsimulate warning light signals on each side of emergency vehicle 104.Furthermore, controller 50 may be used to create multiple warning lightsignals on each side of light bar 70. For example, controller 50 maycreate a simulated revolving blue light positioned at front passengerside 102 of light bar 70, oscillating white lights positioned at frontdriver side 100, and yellow arrows there between. Additional oralternative warning light signals may be produced out the back 18 andsides of light bar 70. It is further envisioned that light bar 70 mayconsist of a single light source, a single row of light source or alarge array of LED's 30 across each side (not shown). This embodimentprovides the largest display and, therefore, is best suited to displaydesired combinations of warning lights and images. It should be notedthat the identified types of warning light signals, combinations and/orpatterns of warning light signals, may also be reproduced through theillumination of a single row of LED light sources 30.

Mechanical rotation and oscillation of warning signal lights 10 aboutaxis A is possible by way of attachment to gyrator 90 depicted in FIG.3. Gyrator 90 mounted to light bar 70, generally comprises electricmotors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of warning signal light 10. Cable 97 is preferablyconnected to a power supply and either an external controller 55 orcontroller 50.

Gyrator 90 may be capable of rotating or oscillating warning signallight 10 about a single or dual axis of rotation A. FIG. 3 shows gyrator90 configured to rotate or oscillate warning signal light 10 about avertical axis A by way of motor 96.1 and oscillate warning signal light10 about a horizontal axis A by way of motor 96.2. Rotation oroscillation of warning signal light 10 about vertical axis A isaccomplished through direct attachment of connecting portion to motor96.1. Oscillation of warning signal light 10 about horizontal axis A isaccomplished by attaching swivel arm 99 to bracket 99.1 and post 99.2which is mounted to motor 96.2.

Alternative methods for imparting rotation or oscillation motion towarning signal light 10 may be accomplished through the use of electricmotors, toothed gears, and worm gears. In addition, maintainingelectrical communication between a power supply and an externalcontroller 55 with a revolving or oscillating warning signal light 10may be accomplished using brushes or other means without sacrificing theoperation of the warning signal light 10.

In another embodiment as depicted in FIGS. 13 and 14, emergency vehicle104 may include a front or rear windshield 106. The front or rearwindshield 106 is generally angularly offset with respect to the vehicleat an approximate angle of 45 degrees. In this embodiment, the mountingof a panel 14 of light sources 30 in flush contact with the interior ofa front or rear windshield 106 occurs through the use of angular offsets108 for the light sources 30 such that light emitted from the lightsources 30 occur at a horizontal visual line (V) which is substantiallyparallel to the plane of a vehicle and not at an approximate angle of 45degrees upward, which corresponds to the angle for the front or rearwindshield 106.

In this embodiment, the ease of visualization of the light source 30 issignificantly enhanced by the downward angular offsets 108 whichposition the light sources 30 along parallel visual lines of sight (V).LED supports 12 or panels 14 may then be positioned in any desiredlocation within the interior of a vehicle in flush contact or proximateto the front or rear windshield 106. A suitable cable 97 is required toprovide electrical power for illumination of the light sources 30. Itshould be noted that the angle of incidence for the angular offsets 108may vary considerably dependent upon the make or model for the vehicleto include the warning signal lights 10.

It should be further noted that the warning signal light 10 may be usedwith an automobile, motorcycle, snowmobile, personal water craft, boat,truck, fire vehicle, helicopter, and/or any other type of vehiclereceptive to the use of warning signal lights 10. It should be furthernoted that LED support 12 or panel 14 may be mounted to the interior topdashboard of a vehicle proximate to the front windshield 106 or to theinterior top rear dashboard proximate to the rear windshield 106 of avehicle.

Mounting of a light support 12 or panel 14 to either the front or reardashboards may minimize the necessity for inclusion of angular offset108 for the light sources 30. It should be further noted that LEDsupports 12 or panels 14 may be releasably affixed to the interior ofthe front or rear windshields 106 via the use of suction cups,hook-and-loop fabric material such as Velcro®, and/or any otherreleasable affixation mechanism at the preference of an individual.

In another alternative embodiment as depicted in FIG. 15, warning signallight 10 may function as a remote, revolving, or stationary beacon. Inthis embodiment, LED support 12 or panel 14 is preferably releasablyconnected to a transportable support 120 via the use of a bracket. Thetransportable support 120 may be a tripod having telescoping legs or maybe any other type of support as preferred by an individual. In thisembodiment, LED light support 12 or panel 14 is electrically connectedto an elongate electrical extension cable 97 which may include anydesired adapter for electrical connection to a power source which may bea vehicle. The remote light support 12 or panel 14 may also includeplug-in adapters for electrical connection to any desired electricalpower source other than a vehicle as is available.

The transportable support 120 may also include gyrator 90 as earlierdescribed to provide a desired rotational or oscillatory motion forwarning signal light 10. A controller 50 having a microprocessor 52 mayalso be integral to, or in electrical communication with, LED's 30 forthe provision of multi-colored lights, flashing, alternating, modulated,moving characters, arrows, stroboscopic, oscillating and/or revolvingwarning light signals as desired by an individual. In this embodiment,the warning signal light 10 may be physically separated from anemergency vehicle 104 any desired distance to facilitate or enhance thesafety of a potentially dangerous situation necessitating the use ofwarning signal lights 10. In addition, it should be noted that a seriesof remote warning signal lights 10 may be electrically coupled to eachother for any desired distance to again facilitate the safety of asituation necessitating the use of warning signal lights 10.

FIG. 16 shows a perspective view of a xenon lamp 1. Xenon lamp 1 has abase pedestal 2 which is typically formed of rubber, plastic, or otherinsulating material. Base pedestal 2 has a top surface 3 which maysupport a glass tube 4 which may have a looped curve such that an anodeend and a cathode end are each supported on a top surface. The anode andcathode ends may be sealed and respective electrical conductors 5 and 6may pass through the sealed ends and through the top surface 3. Atrigger wire 7 may be helically wound about the exterior surface of theglass tube 4 and the ends of the trigger wire 7 may be passed throughthe top surface 3 of the base pedestal 2 to form a third conductor onthe underside of the base pedestal 2.

Base pedestal 2 may have an upper cylinder portion 8 extending from alower shoulder all of which may extend above the top surface 3. Theupper cylindrical portion 8 may include an upper shoulder 9. A glassdome (not shown) may be sized to fit over the xenon lamp 1 and glasstube 4 for resting on the upper shoulder 9. The glass dome may bepreferably made from a transparent or silicate glass material capable ofwithstanding heat stress. The outer diameter of the glass dome istypically about one inch which is sized to fit through the conventionalopening in a typical vehicle lamp fixture. The exterior glass domesurface typically has a much lower temperature during operation than theexterior surface of the glass tube 4 forming a part of the xenon lamp 1.The temperature drop between the glass tube 4 and the glass domefacilitates the use of coloring of the dome to provide a colored lamp byvirtue of the xenon light intensity passing through the colored dome.

The xenon lamp 1 is preferably aligned for insertion into a conventionalopening 248 of a light reflector 260 (FIGS. 20 and 21). The lightreceptacle opening 248 in the light reflector 260 is typically about oneinch in diameter; and the glass dome and base pedestal 2 are preferablysized to fit within the light receptacle opening 248. The xenon lamp 1in its final construction may include a cover plate (not shown) affixedover the bottom opening of the base pedestal 2 for affixation to a lightreflector 260 via the use of screws which pass through the screwapertures 9.1. The anode, cathode, and trigger wire 7 preferablytraverse the base pedestal 2 and may include a plug 9.2 which is adaptedfor engagement to a controller/power supply for a motor vehicle.

The light reflector 260 may be a conventional light reflector of thetype found in vehicles having a clear plastic or glass lens cover. Theglass or lens cover may be fitted over the front edge of the reflector260 in a manner which is conventional with vehicle lamps. It should benoted that the light reflector 260 may be parabolically or other shapedat the preference of an individual. The light reflector 260 may bemounted to a motor for rotation about a vertical axis. In thisembodiment the light source/replacement lamp 200 may be integrallyconnected or affixed to the reflector 260 for simultaneous rotationabout the vertical axis during use of the motor. Alternatively, thelight source/replacement lamp 200 may be fixed proximate to the verticalaxis where the light reflector 260 is rotated around the stationaryreplacement lamp 200 to provide for the visual appearance of arotational light source.

The glass domes as used with the xenon lamps 1 may be colored with anycolor as preferred by an individual including but not limited to red,blue, amber, green, and/or white. It should be noted that the lightfixture incorporating the light reflector 260 may be a headlight fixtureor a turn signal light fixture where the xenon lamp 1 is mounted intothe light reflector 260 on either side of a centrally-mounted halogenlight bulb which may be used as a headlight lamp. In this case, thelight fixture could perform its normal function as a headlight and couldalternatively flash several additional colors, depending upon the needsof the user. This configuration provides an emergency flashing lightconstruction which is wholly concealed within a normal head lamp of avehicle and is, therefore, not readily visible from outside the vehicleunless the lights are flashing. This construction may find applicationin an unmarked emergency vehicles such as might be used by some lawenforcement officers.

In operation, the LED replacement lamp 200 may be constructed as areplacement part for a conventional incandescent or xenon gaseousdischarge lamp. The standard mounting base 204 and LED support assembly212 may be sized to readily fit into the same light opening as anincandescent lamp would require, although it is apparent the electricaldriving circuit for the LED replacement lamp 200 may requiremodifications to accommodate the LED operating principles.

LED warning signal lamp 200 may be used in a variety of locations abouta vehicle. It should be noted that the use of the LED warning signallamps 200 are not necessarily limited to positioning adjacent to thehead lamp or headlight, tail light, or turn signal illumination devicesfor an emergency vehicle 104. The LED warning signal lamp 200 may beused as a rotational, pulsating, or oscillating reflector light withinthe interior adjacent to a front, rear, and/or side window of a vehicle.

It is also envisioned that the controller 50 may control warning signallights 200 independently of one another such that each warning signallamp 200 is capable of producing warning light signals which areindependent and/or different from those produced at another locationabout an emergency vehicle 104. For example, a front left location mayproduce a red colored light while simultaneously a front right locationmay produce an amber colored light and a right rear location may producea green colored light and a left rear location may produce a bluecolored light. The controller 50 may then alternate the color of thelight illuminated from the warning signal lamp 200 in each area asdesired by an individual. Alternatively, the controller 50 maysequentially activate warning signal lamps 200 positioned about anemergency vehicle 104 to simultaneously produce a desired color oralternating sequence of colors. It should also be noted that thecontroller 50 may simultaneously illuminate all LED warning signal lamps200 to produce a flashing or strobe light which may be particularlyuseful in certain emergency situations. It should be further noted thatthe controller 50 may selectively illuminate individual LED warningsignal lamps 200 in any desired color, pattern, and/or combination asdesired by an individual.

The purpose of the LED replacement lampassembly 200 is to replace existing xenon gaseous discharge andincandescent lamps with new LED technology while simultaneouslyutilizing existing standard bases in a standard lamp enclosure. Forexample, an individual may choose to replace a halogen “H-2” 55 wattlamp with an “LED-2” lamp in an existing rotating light fixture with noother structural modifications, yet achieving the advantages of lesspower consumption, greater reliability, easier installation, less RFemissions (which reduces interference with radio or electronicequipment), cooler operating temperatures, simplified circuitry, longerlife, greater durability and duty capability, and simultaneouslyproviding pure and easier-to-see color light output.

As depicted in FIG. 20, a rotational light reflector 246 is disclosed.The rotational light fixture 246 includes a reflector assembly 260having a standard opening 248. The incandescent light assembly 220 ispreferably positioned in the standard opening 248 for extension of thevertical post 224 outwardly from the reflector assembly 260 forpositioning of the light bulb 226 in a desired location.

It should be noted that theindividual LED module lamps 240 are preferably in electricalcommunication with a power source not shown.

It should be further noted that the rotational light fixture 252 mayalso be adapted for the provision of an oscillating or pulsating warninglight signal at the preference of an individual.

An alternative replacement LED lamp 200 is depicted in FIGS. 23-25. Inthis embodiment the LED replacement lamp 200 includes a standardmounting base 270. The standard mounting base 270 also preferablyincludes a plurality of teeth 272. The teeth 272 are preferably adaptedfor mating coupling with gears integral to a motor and/or reflector 260,or rotational light fixture 246 to facilitate rotation and/oroscillation of the replacement LED lamp 200. The standard mounting base270 also preferably includes a top surface 274 opposite to the teeth272.

An upper cylinder portion 276 is preferably adjacent to the top surface274. The upper cylinder portion 276 preferably includes an uppershoulder 278. Extending upwardly from the upper shoulder 278 ispreferably a circuit board, LED mounting surface, or support 280 whichpreferably includes one or more LED illumination sources 282. The LEDillumination sources 282 may be of the same or different colors at thepreference of an individual. A wire 284 is preferably in electricalcommunication with the LED illumination sources 282 to provide forcommunication and contact with the controller 50 for combination and/orindividual illumination of the LED illumination sources 282. A standardplug-in connector may be integral to the wire 284 to facilitate couplingengagement to the controller 50 and/or power source for a vehicle 104.

The circuit board or LED mounting surface 280 is preferably adapted tohave a first side 286 and an opposite side 288. Preferably a pluralityof LED illumination sources 282 are disposed on both the first side 286and the opposite side 288 of the replacement lamp 200.

A glass dome or protector 290 is preferably adapted for positioning overthe circuit board or LED mounting surface 280 for sealing engagement tothe top surface 274 of the standard mounting base 270. The glass dome290 may be formed of transparent plastic material or a transparent orsilicate glass material capable of withstanding heat stress at thepreference of an individual. It should be further noted that the glassdome 290 preferably protects the circuit board or LED mounting surface280 and the LED illumination sources 282 from contamination and fromexposure to moisture during use of the replacement lamp 200. In thisregard, the sealing lip 292 of the glass dome 290 preferably is securelyaffixed to the top surface 274 to effectuate sealing engagementtherebetween. The outer diameter of the glass dome 290 is preferablyabout one inch which is sized to fit within the conventional opening 248in a typical lamp fixture or reflector assembly 260.

The replacement lamp 200 depicted in FIGS. 23, 24, and 25 is alsoadapted to be positioned in a one inch light receptacle opening 248which has been placed into a reflector assembly 260. Illumination of oneor more individual LED illumination sources 282 as disposed on thecircuit board or LED mounting surface 280 enables the replacement lamp200 to take on the appearance of a warning signal or emergency signalinglamp.

The replacement lamp as depicted in FIGS. 23, 24, and 25 mayalternatively permit the circuit board 280 to extend below the uppershoulder 278 to facilitate affixation and positioning relative to thestandard mounting base 270.

The controller 50 may regulate the illumination of the LED light sources282 individually, or in combination, to provide a desired warninglighting effect for the replacement lamp 200. Also, the controller 50may illuminate the LED light sources 282 individually, or incombination, independently with respect to the first side 286 and theopposite side 288 to provide different warning light effects to beobserved by an individual dependant upon the location of the personrelative to the replacement lamp 200. The controller 50 may alsosimultaneously or independently regulate the power intensity to the LEDillumination sources 282 to provide for a modulated or variable lightintensity for observation by an individual. It should also be noted thatthe LED illumination sources 282 may be formed of the same or differentcolors at the preference of an individual to provide a desired type ofwarning light effect for the replacement lamp 200.

In an alternative embodiment, the LED warning signal lamps 10 or LEDreplacement lamps 200 may be electrically coupled to a controller 50which in turn is used to provide a modulated power intensity for thelight source. A modulated power intensity enables the provision ofvarious power output or patterns of illumination for creation of aplurality of visually distinct warning light signals without the use ofmechanical devices. In these embodiments, the controller 50 illuminatesselected light sources 282 and the controller 50 may also regulateand/or modulate the power supplied to the light source 282 therebyvarying the intensity of the observed light. In addition, the controller50 may modulate the power supplied to the LED warning signal lamps 10 orLED replacement lamps 200 in accordance with a sine wave pattern havinga range of 0 to full intensity. At the instant of full intensity, thecontroller 50 may also signal or regulate a power burst for observationby an individual. The controller 50 operating to regulate and/ormodulate the power intensity for the warning signal lamps 10 or LEDreplacement lamps 200 in conjunction with illumination andnon-illumination of selected light source 282 may establish theappearance of a rotational warning light source or pulsating lightsource without the necessity of mechanical rotational or oscillatingdevices. The current draw requirements upon the electrical system of anemergency vehicle 104 is thereby significantly reduced. Spatialconsiderations for an emergency vehicle are also preferably optimized byelimination of mechanical, rotational and/or oscillation devices.

The controller 50 may also regulate the modulated power intensity forthe provision of a unique variable intensity warning light signal. Theunique variable intensity light source is not required to cycle througha zero intensity phase. It is anticipated that in this embodiment thatthe range of intensity will cycle from any desired level between zeropower to full power. A range of power intensity may be provided betweenthirty percent to full power and back to thirty percent as regulated bythe controller 50. It should also be further noted that an irregularpattern of variable power intensity may be utilized to create a desiredtype of warning light effect. In addition, the controller 50 may alsosequentially illuminate adjacent columns 32 to provide a unique variablerotational, alternating, oscillating, pulsating, flashing, and/orcombination variable rotational, alternating, pulsating, oscillating, orflashing visual warning light effects. A pulsating warning light signalmay therefore be provided through the use of modulated power intensityto create a varying visual illumination or intensity effect without theuse of rotational or oscillating devices. The controller 50 may alsomodulate the power intensity for any combination of light sources 30 or282 to provide a distinctive or unique type of warning light signal.

The use of a controller 50 to provide a modulated power intensity for alight source may be implemented in conjunction with replacement lamps200, flexible circuit boards having LED light sources 30, paneledcircuit boards or LED mounting surfaces having LED light sources 30,light bars 70 having LED light sources 30, a cylindrical, square,rectangular, or triangular-shaped circuit boards having LED lightsources 30 and/or any other type or shape of LED light sources includingbut not limited to the types depicted in FIGS. 1-50 herein.

Further, the controller 50 may be utilized to simultaneously providemodulated or variable light intensity to different and/or independentsections, areas, and/or sectors 326 of a light source (FIG. 35). Also,the controller 50 may be utilized to simultaneously provide modulated orvariable light intensity to different and/or independent sectors, areas,and/or sections 326 of the forward facing side or rearward facing sideof the light bar 70 for the provision of different warning light signalsor a different warning light effects on each side. In this embodiment itis not required that the forward facing and rearward facing sides of thelight bar 70 emit the identical visual patterns of illuminated lightsources 30. The controller 50 may regulate and modulate the variablelight intensity of any desired sector 326 of the forward facing sideindependently from the rearward facing side of the light bar 70. Thecontroller 50 may thereby provide any desired pattern and/or combinationof patterns of warning light signals through the utilization of variableand/or modulated light intensity for the forward facing side, and adifferent type or set of patterns and/or combination of patterns ofwarning light signals having variable or modulated light intensity forthe rearward facing side of the light bar 70 as desired by anindividual. It should be further noted that an infinite variety ofpatterns and/or combinations of patterns of warning light signals may beprovided for the forward facing side and the rearward facing side of thelight bar 70 a the preference of an individual.

The use of the controller 50 to modulate the power intensity for a lightsource 30 to provide a unique warning light signal may be utilizedwithin any embodiment of an LED light source 10, light bar 70 lightsupport, replacement lamp 200 or reflector assembly as described inFIGS. 1-50 herein.

It should be further noted that the modulation of the power intensityfor a light source 30 or replacement lamp 200 may be used inconjunction, or as a replacement to, the sequential illumination ofrows, columns, and/or individual LED light sources 30 to provide adesired type of unique warning light effect.

The modulated power intensity may be regulated by the controller 50 tocreate a unique warning light signal within a single sector 326 or inconjunction with multiple separated or adjacent sectors 326 of light bar70 or light support for the provision of any desired composite emergencywarning light signal. All individual LED light sources 30 within a lightbar 70 or light support may be simultaneously exposed to incrementallyincreased modulated power intensity to provide for an incrementalincrease in illumination. A power burst at full power may be provided atthe discretion of an individual. The modulation of the power intensityin conjunction with the incremental increase in illumination of all LEDlight sources 30 within light bar 70 or light support may provide theappearance of rotation of a warning light signal when observed by anindividual. The power exposed to the individual light sources 30 maythen be incrementally decreased at the preference of an individual. Itshould be noted that the power is not required to be regularlyincrementally increased or decreased or terminated. It is anticipatedthat any pulsating and/or modulated variable light intensity may beprovided by the controller 50 to the LED light sources 30.

It should also be noted that all individual LED light sources 30 withina light bar 70 are not required to be simultaneously and incrementallyilluminated to provide for the appearance of rotation. For example, alight bar 70 or light support may be separated into one or more distinctsegments 326 which are formed of one or more columns 32 of LED lightsources 30, a particular segment 326 may be selected as a centralillumination band which may receive the greatest exposure to themodulated or variable power intensity and, therefore, provide thebrightest observable light signal. An adjacent segment 332 may bedisposed on each side of the central illumination band 330 which in turnmay receive modulated or variable power intensity of reduced magnitudeas compared to the central illumination band 330. A pair of removedsegments 333 may be adjacent and exterior to the segments 332, and inturn, may receive exposure to a modulated power source of reducedintensity as compared to segments 332. The number of desired segmentsmay naturally vary at the discretion of an individual. The controller 50may thereby regulate a power source to provide a modulated or variablepower intensity to each individual segment 330, 332, or 333 (FIG. 35) toprovide for a unique warning light effect for the light bar 70 or lightsupport.

It should be further noted that light supports 12 may be flat and rigid,pliable, moldable, triangular, cylindrical, partially cylindrical,and/or any other shape as desired by an individual provided that theessential functions, features, and attributes described herein are notsacrificed.

The provision of a modulated power intensity to the light bar 70 orlight support may also be coupled with or in combination to thesequential illumination of columns 32 as earlier described. In thissituation, the warning light signal may initially be dim or off as theindividual columns 32 are sequentially illuminated and extinguished forillumination of an adjacent column or columns 32. The power intensityfor the illuminated column or columns 32 may simultaneously beincrementally increased for a combination unique rotational andpulsating modulated or variable warning light signal. In addition, thecontroller 50 may be programmed to provide the appearance of rotationpulsation and/or oscillation at the discretion of an individual.

Each individual LED light source 30 preferably provides an energy lightoutput of between 20 and 200 or more lumens as desired by an individual.

Each light support 12 may contain a plurality of rows 34 and columns 32of individual LED light sources 30. The light supports 12 are preferablyin electrical communication with the controller 50 and power supply. Thesupports 12 preferably are controlled individually to create a desiredwarning light signal for an emergency vehicle 104 such as rotation,alternating, oscillation, strobe, flashing, or pulsating as preferred byan individual. Each support 12 may be controlled as part of an overallwarning light signal or pattern where individual supports 12 may beilluminated to provide a desired type or combination light signal inaddition to the provision of a modulated or variable power intensity forthe light source 30.

Modulated power intensity may be regulated by the controller 50 tocreate the appearance of rotation within a single support 12 or inconjunction with multiple separated, independent or adjacent supports 12for the provision of a composite emergency warning light signal.

It should be noted that each portion, section, sector, or area 326 oflight bar 70 or light support may be controlled as part of an overallwarning light signal or pattern where individual sections or sectors 326may be illuminated to provide a desired type of warning light signalincluding but not limited to rotation and/or oscillation through the useof a modulated or variable power intensity. Alternatively, thecontroller 50 may provide for the random generation of light signalswithout the use of a preset pattern at the preference of an individual.

Controller 50 may be used to selectively activate individual LED's 30 tocreate a pulsating light signal, a strobe light signal, a flashing lightsignal, an alternating light signal, and/or an alternating coloredflashing light signal for an emergency vehicle.

Controller 50 provides a means for activating LED's 30 individually toallow for greater flexibility in the type of warning light signalcreated. This embodiment of the invention is also capable of displayinginformation in a variety of different colors or sequential illuminationof colors.

Eachindividual LED light source 306 as included within a strip LED lightsource 308 may be enclosed within a reflector 370 to facilitate andmaximize light output along a desired visual line of sight. It should benoted that the LED light sources 306 preferably have maximumillumination at an angle of incidence approximately 40°-45° downwardlyfrom vertical. The strip LED light sources 308 preferably include aback-side. The back-side preferably includes an adhesive, magnetic, orother affixation device which may be used to secure the strip LED lightsources 308 to the exterior of an emergency vehicle 300 in any desiredpattern or location. The strip LED light sources 308 may also beenclosed within a transparent cover 324 which prevents moisture or othercontamination from adversely affecting the performance of the LED lightsources 306 during use of the strip LED light source 308.

Wires of adjacent strip LED light sources 308 may preferably beintertwined to extend across a vehicle for coupling to a power supply ata central location. The wires are preferably connected to the controller50 which may be used to regulate the illumination of individual LEDlight sources 306 and/or individual panels of the strip LED lightsources 308 to provide for the appearance of sequential, pulsating,alternating, oscillating, strobe, flashing, modulated, and/or rotationallights for an emergency vehicle 300. It should be noted that theindividual LED light sources 306 within the strip LED light source 308may be of a single or variety of colors as desired by an individual.Alternatively, adjacent strip LED light sources 308 may be electricallycoupled to each other in a parallel or series electrical connection forcommunication to a centrally located controller and power source.

The individual LED light sources 306 as incorporated into the array 312of the strip LED light sources 308 are preferably sturdy and do not failor separate from a vehicle 300 when exposed to rough operatingconditions. It should be further noted that any individual strip of LEDlight sources 308 may be easily replaced as required.

Each individual LED light source 306 preferably provides anenergy light output of between 20 and 200 or more lumens as desired byan individual.

The strip LED light sources 308 may individually be any size aspreferred by an individual. It is anticipated that the strip LED lightsources 308 may have the approximate dimensions of three inches inlength, three inches in width, and one-half inch in thickness for use inaffixation to the exterior of an emergency vehicle 300.

It should be noted, however, that any desired size of strip LED lightsources 308 may be selected by an individual for use in association withthe exterior of the emergency vehicle 300 including the use of a seriesof solitary light sources 306.

Referring to FIG. 35, a panel 304 of individual LED light sources 306 isdepicted. The panel 304 may form the illumination element for the stripof LED light sources 308 and/or light bar 70 or light support 12, 302 asaffixed to an emergency vehicle 300. Each panel 304 preferably containsa plurality of rows 34 and columns 32, 328 of individual LED lightsources 306. The panels 304 are preferably in electrical communicationwith the controller 50 and power supply (now shown). The panels 304preferably are controlled individually to create a desired warning lightsignal for an emergency vehicle 300 such as rotation, alternating,pulsating, sequencing, oscillation, modulated strobe, or flashing aspreferred by an individual. Each panel 304 may be controlled as part ofan overall warning light signal or pattern where individual panels 304may be illuminated to provide the appearance of rotation and/oroscillation motion through the use of a modulated power intensity lightsource without the use of mechanical devices.

It should also be noted that the strip LED light sources 308 may beorganized into distinct sections, segments, and/or sectors 326 forindividual illumination by the controller 50. Each distinct segment,section, and/or sector 326 may therefore be illuminated with a visuallydifferent and distinct type of light signal with, or without, modulatedor variable power intensity for the creation of a desired type of uniquewarning lighting effect for a vehicle. An infinite variety of colorand/or pattern combinations or sequences may be established for theemergency vehicle 300 through the use of the controller 50.

Modulated power intensity may be regulated by the controller 50 tocreate the appearance of rotation or pulsation within a single panel304, strip 308, or in conjunction with multiple separated or adjacentpanels 304 or strips 308 for the provision of a composite warning lightsignal as desired by an individual. The warning light signal for each ora group of panels 304 or strips 308 may also be regulated by thecontroller 50 for the provision of a modulated power intensity for anobservable warning light signal. All individual LED light sources 306within a panel 304 or strip 308 may also be exposed to incrementallyincreased modulated power intensity to provide for an incrementalincrease in illumination for a warning light signal. The modulation ofthe power intensity of LED light sources 306 within panel 304 or strips308 thereby may provide the appearance of rotation of a light signalwhen observed by an individual. The power modulation or light intensitycurve is anticipated to resemble a sine wave pattern when the warninglight signal provides the appearance of rotation (FIG. 43). The power tothe individual light sources 306 may then be incrementally decreased atthe preference of an individual. It should be noted that the power isnot required to be terminated. It should also be noted that eachindividual LED light source 306 is not required to receive the samelevel of power output from the controller 50. Therefore differentindividual LED light sources 306 may receive different power outputlevels within a single warning light signal. Individual LED lightsources 306 within panel 304 are not required to be simultaneously andincrementally illuminated to provide for the appearance of rotation. Itis anticipated that a pulsating and/or modulated variable lightintensity may be provided by the controller 50 for regulation of thepower output from thirty percent to maximum and back to thirty percentwhich affords a desirable type of pulsating modulated variable lighteffect.

The provision of a modulated power intensity to the panels 304 may alsobe coupled with or in combination to the sequential illumination ofcolumns 328 as earlier described. In this situation, the warning lightsignal may initially be dim or off as the individual columns 328 aresequentially illuminated and extinguished for illumination of anadjacent column or columns 328. The power intensity for the illuminatedcolumn or columns 328 may simultaneously be incrementally increased fora combination unique rotational and pulsating modulated light signal. Inaddition, the controller 50 may be programmed to provide the appearanceof rotation pulsation and/or oscillation at the discretion of anindividual.

It should be noted that the provision of a modulated light or powerintensity may be implemented in association with a light bar or lightsupport 302, a cylindrical panel, a strip of lights 308, flat panels304, or any other type of light source as desired by an individual foruse with an emergency vehicle 300.

Referring to FIGS. 48 and 49, an individual LED light source 306 isdepicted in detail. The LED light source 306 preferably include aceramic and/or heat resistant base 334. Centrally within the ceramic andheat-resistant base 334 is positioned a light source 336. The lightsource 336 is preferably enclosed within a protective cover 338.Extending outwardly from the individual light source 306 are a pair ofcontact paddles 340 which preferably provide for the electrical contactsfor illumination of the light sources 336 during use of the individuallight sources 306. The back of the LED light source 306 includes a slug342. The slug 342 is designed to be positioned within circular openings344 of a circuit board or LED mounting surface 346 (FIG. 36). Thecircuit board or LED mounting surface 346 preferably establishes a heatsink within an aluminum base or frame 348 as depicted in FIGS. 38 and39. The LED light sources 306 as depicted in FIGS. 48 and 49 preferablyprovide for a light intensity varying between 20 and 200 lumens orhigher at the discretion of an individual. The positioning of the slug342 in the circular openings 344 of the circuit board or LED mountingsurface 346 also preferably establishes a heat sink. A heat sink isdesirable because the individual LED light sources 306 may have asufficient level of power output during use to develop heat. As aresult, the slugs 342 are positioned within the circular opening 344 andmay be fully engaged to an adhesive for affixation to an aluminum base349 (FIGS. 38 and 39). This combination assists in the dissipation ofheat during use of the individual LED light sources 306 enhancing theperformance of the light support 302.

As may be seen in FIGS. 31, 32, 37 and 50, in an alternative embodiment,the light bar or light support 302 or panel 304 may be formed of asingle row of LED light sources 306. Within this embodiment, the LEDlight sources 306 are positioned within circular openings 344 of circuitboard or LED mounting surface 346 (FIG. 37). Circuit board 346 may beaffixed to aluminum base 348 through the use of adhesive including glassbeads where the circular openings 344 preferably establish a heat sinkfor the individual LED light sources 306. The use of adhesive includingglass beads to affix the LED light sources 306 and circuit board 346 tothe aluminum base 348 preferably assists in the creation of electricalcontact for the light bar or light support 302.

As depicted in FIG. 37 the top surface of the circuit board or LEDmounting surface 346 may include two reflectors or mirrors 350. Thereflectors or mirrors 350 are preferably elongate and are positionedsubstantially parallel to each other and are adjacent or aligned to therows of individual LED's 306. The reflectors or mirrors 350 preferablydiverge upwardly and outwardly from a position proximate to the LEDlight source 306 and aluminum base 348. As such, the mirrors 350 have aseparation distance which is narrow proximate to the LED light sources306, where the separation distance becomes larger as the distancevertically from the aluminum base 348 increases.

As earlier described, the brightest or most intense light of theindividual LED light sources 306 is provided at an acute angle ofapproximately 40° to 42°. The reflector or mirror 350 as angled upwardlyand outwardly relative to the row of LED light sources 306 reflectslight exiting the LED light sources 306 along a desired line of sightwhich corresponds to perpendicular observation by an individual. Thereflectors or mirrors 350 maximize the efficiency of the light sources306 by reflecting light along the line of sight to be observed by anindividual during an emergency situation. The reflectors or mirrors 350may have a polished or non-polished surface at the preference of anindividual depending on the brightness desired for the light support302. The reflectors or mirrors 350 may also include one or morereflective sections 374 and/or transparent or clear sections 372. Thetransparent or clear sections 372 and the reflective sections 374 aredescribed in detail with reference to FIGS. 27-30 herein. It should benoted that the surface of the reflectors or mirrors 350 may include anydesired combination of sections, patterns, stripes, rows, and/or columnsof clear or transparent sections 372 and/or reflective sections 374 asdesired by an individual for a reflection of light illuminated from theindividual LED light sources 306 during the provision of a warning lightsignal.

Wires 354 preferably connect the circuit board 346 to the power supplyand controller 50. A modulated power source as earlier described maythereby be provided to the light support 302 which includes thereflector or mirrors 350. In this embodiment, the sequentialillumination of individual LED's 306 may occur to provide a desired typeof warning light signal. Also, the circuit board 346 as engaged to thebase 348 may be separated into segments 326 of LED light sources 306 foruse in combination with a modulated power intensity electrical source.

As depicted in FIGS. 38 and 39, the frame 348 includes a base 349. Thebase 349 may include a holding cavity 358. In the holding cavity 358 ispreferably positioned a circuit board or LED mounting surface 360 whichincludes a plurality of circular openings 344. In each circular opening344, is preferably positioned an individual LED light source 306. Abovethe holding cavity 358 is preferably a first support 362 and a secondsupport 363. The first support 362 and second support 363 preferablyhave an angled interior edge 364. Each angled interior edge 364 ispreferably adapted to receive a reflector or mirror 350. Each mirror 350is preferably utilized to reflect light illuminated from an individuallight source 306 along a visual line of sight as depicted by arrow AA ofFIG. 39. The first and second supports 362, 363 also preferably includea positioning ledge or notch 366 which is adapted to receive a glass ortransparent plastic cover lens 368 which serves as a protector for theframe 348 and individual LED light sources 306.

Referring to FIG. 50, the frame 348 may be elongate having a first end380 and a second end (not shown). The first end 380 and the second endpreferably each include and affixation area 382 which may be threadedfor receiving engagement to a fastener 384 as preferred by anindividual. A bracket 386 may be rotatably engaged to the first end 380and second end at the preference of an individual by tightening of thefasteners 384 relative to the affixation areas 382. The bracket 386preferably includes and angled portion 388 which may include a secondfastener 390 which may include suction cups. Alternatively, the secondfastener 390 may be screws, bolts, and/or rivets for attachment of theframe 348 at a desired location relative to the interior or exterior ofa vehicle 300.

Referring to FIGS. 26-30, a reflector or culminator for the individualLED light sources 306 is disclosed. The reflector or culminator isindicated in general by the numeral 370. The reflector or culminator 370may be conical in shape and may be configured to encircle an individualLED light source 306. The reflector or culminator 370 may be partiallytransparent. The reflectors 370 may have a clear section 372 and areflective section 374. In FIG. 29, the clear section 372 is preferablypositioned proximate to the LED light source 306 and the reflectivesection 374 is preferably positioned to the top of the reflector 370.

In FIG. 28, the reflective section 374 is preferably positionedproximate to the LED light source 306 and the clear section 372 ispreferably positioned to the top of reflector or culminator 370. As maybe seen in FIG. 30, the entire interior surface of the reflector orculminator 370 may be formed of a reflective section 374. It should benoted that any combination of clear sections 372 and reflective sections374 may be utilized at the discretion of an individual. It should benoted that a plurality of clear sections 374 may be utilized within eachreflector or culminator 370 at the discretion of an individual.

The use of a combination of clear sections 372 and reflective sections374 enable an individual to select a configuration for the provision ofpartial illumination along an angle which is not parallel to a desiredline of sight. An individual may thereby be able to observe anilluminated light signal from the side or top of a light bar or lightsupport 302 as opposed to being aligned with a desired line of sight.

Each of the culminator or reflector cup 370 preferably includes anangled interior surface which extends upwardly and diverges outwardlyfrom a central opening 394. Each central opening 394 is preferablyconstructed and adapted for positioning approximate to and over an LEDlight source 306. Each of the culminator or reflector cups 370 alsopreferably includes an angled exterior surface which extends upwardlyand diverges outwardly from a bottom or base which is preferablypositioned approximate to an LED mounting surface or circuit board 346.

Referring to FIG. 26 an array of culminator cups or reflectors 270 maybe formed into a culminator assembly or array 392. The culminatorassembly or array 392 is preferably adapted for positioning over anarray of LED light sources 306. Examples of arrays of LED light sources306 which may be utilized with a culminator assembly 392 are depicted inFIGS. 3-10, 12, 14, 15, 23-25, 31, 32, 34, 35, 37, 39, 40, 44, and 47.

Each culminator array 392 is preferably formed of a reflective materialwhich has plurality of reflective cups 370 disposed there through. Eachopening 394 is adapted for positioning over an LED light source 306. Theculminator array 392 preferably has a sufficient thickness to establishan interior reflective surface having a sufficient dimension to reflectlight as emitted from the LED light sources 306. Alternatively, theinterior surface of each reflector cup 370 may be entirely or partiallycoated with reflective material at the discretion of an individual. Itshould be noted that the entire culminator assembly 392 is not requiredto be formed of reflective material if the interior surface of thereflector cups 370 are coated with reflective material.

The culminator array 392 may be formed in any shape as desired by anindividual including but not necessarily limited to square, rectangular,triangular, linear, circular, oval, and special or other irregularshapes for use in reflecting light emitted from an LED light source 306.The interior surface of any desired number of culminator cups 370 mayalso be coated with reflective 374 and non-reflective 372 sections asearlier described.

It should be noted that the strip LED light source 308 and LED lightsources 306 in frame 348 are preferably designed to operate on a 12 voltpower supply which is available in a standard emergency vehicle battery.It should also be noted that the frame 348 and strip LED light source308 are preferably enclosed in a waterproof protector to minimize therisk of contamination or failure from any exposure to moisture or dustor dirt. The use of the strip LED light sources 308 and frame 348preferably minimize the necessity to modify the exterior of an emergencyvehicle 300 through the placement of holes or other apertures. In theseembodiments, the wires 354 and 316 may be adhesively secured to theexterior of a vehicle for entry into the power source and controller 50at a common location.

It should be noted that the strip LED light source 308 may be used onother devices and are not necessarily limited to use on an emergencyvehicle 300. It is anticipated that the strip LED light sources 308 maybe used on a variety of apparatus including but not limited tosnowmobiles, water craft, helmets, airplanes, or any other device whichmay accept use of an LED light source.

In FIGS. 40-43 a warning signal light 400 is depicted which in generalincludes a light source 402 and a rotatable reflector 404. The lightsource 402 may include one or more individual LED illumination devices406. The light source 402 may include a base 408 which may be mounted ona post 410. The light source 402 may either be stationary or rotate atthe preference of an individual.

A motor 412 is preferably electrically connected to a power supply forrotation of a wheel or gear 414. The wheel or gear 414 is connected tothe motor 412 by a shaft 416. The wheel or gear 414 is in contact with,or is engaged to, a rotatable collar 418 which may be adapted to rotatefreely about the post 410 during operation of the motor 412. The wheelor gear 414 may be formed of rubber material or any other desiredmaterial as preferred by an individual. Alternatively, the wheel 414 mayinclude teeth and function as a gear for engagement to correspondinggrooves and teeth as integral to the exterior surface of the collar 418.

An aperture 420 may pass through post 410 to receive wires 422 for theprovision of power to LED light source 402. A washer or support device424 vertically supports rotatable collar 418 on post 410 from a positionbelow collar 418. A positioner 426 functions to restrict the verticalmovement of the collar 418 upwardly during engagement of the motor 412and rotation of the wheel 414 and collar 418.

A horizontal support arm 428 extends outwardly from collar 418. Avertical support arm 430 extends upwardly form horizontal support arm428. Angular support arm 432 extends inwardly and upwardly from verticalsupport arm 430 for positioning of a reflector or mirror 434 above lightsource 402. The reflector or mirror 434 is preferably positioned at anapproximate angle of forty-five degrees relative to the light source402. Light as emitted vertically from the light source 402 may thenreflect from the reflector 434 along a substantially perpendicular lineof visual sight. The reflector 434 rotated ninety degrees is depicted inphantom line as an oval due to the angular offset of approximatelyforty-five degrees.

The use of motor 412 rotates wheel 414 which in turn rotates collar 418and reflector 434 in a circular direction about light source 402 for theprovision of an observed rotational warning light source. In addition,the light source 402 may be electrically coupled to a controller 50 toprovide a modulated, alternating, variable, pulsating, or oscillatinglight source at the preference of an individual simultaneously to therotation of the reflector 434 about light source 402.

Referring to FIG. 41 the warning signal light 400 includes a lightsource 402 which is rotatable in conjunction with the reflector 434. Inthis embodiment the motor 412 is connected to a first gear which isenclosed within casing 436. A second gear is also enclosed within casing436 and is coupled to the first gear for rotation of the reflector 434.A vertical rod 438 is preferably affixed or integral to the second gear.The vertical rod 438 supports the LED light source 402 as positionedadjacent to reflector 434. An angled brace 440 is also preferablyengaged to rod 438. Angled brace 440 supports reflector 434 duringrotation of reflector 434 which represents a circular motion as depictedby arrow 442. In this embodiment reflector 434 is arcuate in shape andmay be parabolic at the discretion of an individual. Light emitted fromlight source 402 may then be reflected by the arcuate reflector 434along a desired line of sight. The engagement of the motor 412 rotatesthe light source 402 and reflector 434 to provide a rotational lightsource as observed by an individual. It should also be noted that thelight source 402 may be coupled to a controller 50 to provide for amodulated, alternating variable, and/or pulsating light signal inconjunction with the rotation of the reflector 434.

Referring to FIG. 42, the reflector 434 is not required to be flat andmay include a convex or concave face 444. The provision of a convex orconcave face 444, is utilized to assist in the creation of a uniquevariable light effect as observed by an individual. Light as emittedfrom the light source 402 may then be reflected at any desired angleother than perpendicular for observation by an individual. The pulsatingintensity of the light as observed by an individual may then be unique,especially when used in conjunction with the rotated reflector 434 andvariable or modulated power intensity from the controller 50. Inaddition, the use of a convex or concave reflector 444 may expand orenhance the observation of the warning signal light 400 by individualsbeyond a perpendicular line of sight. The warning signal light 400 maythen be observed above or below a light source 402. The reflector 434 asrotated ninety degrees is depicted in phantom line and is generallyoblong or oval in shape.

FIG. 43 represents graphically the variable or pulsating illumination ofthe observed light as reflected from the reflector 434 of FIG. 42. Timeis represented along the x-axis and increasing brightness is depictedalong the y-axis. The graph of FIG. 43 shows the gradual increase inbrightness of the observed light as the reflector 434 is rotated to amaximum illumination corresponding to direct in line observation of thewarning light signal and then the gradual decrease in observed lightintensity as the reflector 434 is rotated away from direct in linesight. It should be noted that the observed warning light signal is notrequired to be extinguished and may be reduced to a minimum observableintensity of approximately thirty percent.

Referring to FIG. 44, the warning signal light 400 in general includes alight source 402 which may be rotated through the use of a motor 412 fortransmission of light through a filter 446 for reflection from a conicalreflector 448 as mounted to the interior of a light bar or light support450.

Power for motor 412 is supplied through wires 452 from a power sourcenot shown. Power for the light sources 402 is provided through wires 454in support 456. Brushes 458 may be in electrical communication with thepower from the wires 454 to transmit electrical current to a second setof brushes 460 utilized to communicate power to the light sources 402.The base 462 of the light source 402 may preferably be formed of anelectrically conductive material to facilitate the provision of power tothe light sources 402.

A shaft 464 preferably extends between the motor 412 and the base 462where operation of the motor 412 rotates the shaft 464 and the base 462having the light sources 402. Light is transmitted vertically upwardfrom the light sources 402 through the filter 446. (FIGS. 44 and 45.)The filter 446 may include one or more sections of tinted material 466.The filter 446 may be stationary or may be rotatable at the discretionof an individual. The tinted material 466 may be any color as desired byan individual or opaque to establish a desired illumination effect foran emergency warning signal light. Any number of tinted sections 466 ortransparent areas may be placed on the filter 446. The filter 446 may beformed of glass or plastic or other sturdy material at the preference ofan individual. The tinted sections 466 may be integral to or placed uponthe filter 446 as desired. The filter 446 may be attached to the conicalreflector 448 by a fastener 468.

The conical reflector 448 preferably includes a straight reflective edge470. Alternatively, the reflective edge 470 may be concave or convex asdesired by an individual to establish a unique lighting effect. Theconical reflector 448 is preferably affixed to and descends from the topof a light bar or light support 450 as may be attached to an emergencyvehicle 300.

Light transmitted upwardly from the light sources 402 passes througheither a substantially transparent section or through the tinted oropaque material 466 which may block light transmission or alter thecolor of the light as desired. Light is then reflected from the conicalreflector 448 at a desired angle for transmission through the verticalsections of the light bar or light support 450 for observation by anindividual.

FIG. 46 represents graphically the intensity of the observed light asreflected from the conical reflector 448 of FIG. 44. Time is representedalong the x-axis and observed brightness is represented along they-axis. The observed light signal transmitted from the warning signallight of FIG. 44 is much steeper which corresponds to a shorter periodof observation more similar to a flashing light signal. It should benoted that the light sources may also be coupled to a controller 50 forthe provision of a variable, modulated and/or pulsating light effect.

An affixation opening 508 preferablytraverses the forward face 498 proximate to each of the pair of endfaces 500. A fastener 510 preferably passes through the affixationopening 508 for engagement to the opening 490 to secure the LED mountingsurface 482 into the receiving notch 506. It should be noted that theculminator assembly 484 is then positioned within the interior of thecover 324 where the top surface 496 is proximate to the forward face498. The illumination of the LED light sources 306 then transmits lightthrough the forward face 498 for observation of an emergency warninglight signal.

It should be furthernoted that the engagement of the motor 520 for rotation of the gear 524simultaneously rotates the first support 526, second support 536 andthird support 538 for the provision of a warning light signal.

LED technology enables the selection of a desired wave length fortransmission of light energy from the individual LED light sources 306.Any wave length of visible or non-visible light is available fortransmission from the LED light sources 306. As such, generally nofilters are required for use with individual LED light sources 306. Theindividual LED light sources 306 may be selected to provide for anydesired color normally associated with the use in emergency vehiclessuch as amber, red, yellow, blue, green and/or white.

It should be further noted that the controller 50 may simultaneouslydisplay any number of combinations of warning light signals. Forexample, the controller 50 may provide for a solitary light signal fortransmission from a light source. Alternatively, the controller 50 mayeffect the transmission of two signals simultaneously from the identicallight source where a first warning light signal is emitted from oneportion of the light source and a second warning light signal is emittedfrom a second portion of the light source. Alternatively, the controller50 may alternate the two warning light signals where the first area ofthe light source first transmits a first warning light signal andsecondly transmits a second warning light signal. The second area of thelight source initially transmits the second warning light signal andthen transmits the first warning light signal. Further, the controllermay transmit two independent and visually distinct warning light signalssimultaneously within different areas of light source. The controller 50may also reverse the warning light signals for simultaneous transmissionbetween different areas of the light source. Further, the controller 50may regulate the transmission of more than two visually distinct typesof warning light signals from a light source at any given moment. Thecontroller 50 may alternate warning light signals within different areasor enable transmission of warning light signals in reverse alternatingorder for the creation of an infinite variety of patterns of visuallydistinct warning light signals for use within an emergency situation.The controller 50 may also permit the transmission of a repetitivepattern of warning light signals or a random pattern of visuallydistinct warning light signals at the preference of an individual.

Turning to the embodiment shown in FIG. 51. FIG. 51 shows a possibleconfiguration of a warning signal light 600 having modular components.In the embodiment shown a light support 602 has a plurality of modulereceiving ports 604. The module receiving ports 604 are constructed andarranged to provide electrical communication respectively to a modulesupport member 610 of a module 606 received therein. Each of the modulesupport members 610 may be made up of connection teeth or contacts 608which electrically contact and engage the receiving ports 604 wheninserted therein. Each module 606 has at least one visible light signaldisplay surface 612 which has one or more light sources 30 removablymounted thereon. Preferably the light sources 30 are light emittingdiodes, such as have been previously discussed. About each light source30 may be a culminator 370 as earlier described. Furthermore, eachculminator 370 may include a reflective surface 616 at least partiallydisposed thereon. Reflector 616 more efficiently direct the lightemitted from light source 30 in a desired direction. In an additionalembodiment of the invention the reflector 616 may be adjustable so as toredirect and/or focus light emitted from the light source 30 during use.Also, the visible surface 612 or the individual culminator cup 370 andreflectors 616 may also have one or more lenses equipped thereon toprovide the warning signal light with the ability to magnify and/ordiffuse emitted light as may be desired.

In the embodiment shown, the module support members 610 and the modulereceiving ports 604 respectively are uniform in size. The uniformity ofthe ports 604 and the members 610 allows modules 606 to be readilyreplaced and also provides the invention with the capacity to havevariously sized and shaped modules 606 to be interchanged and arrangedin various configurations as desired by a user. For example a relativelyelongated module, such as is indicated by reference numeral 606 a, couldbe positioned in any of the various ports 604 shown and could likewisebe replaced with any other module such as the more vertically orientedmodule 606 b, or the remaining module type 606 c. Such modularity andstandardization of connections provides the present invention with atremendous variety of module configurations which may be readilyreconfigured as desired.

In addition to providing a variety of module types, the presentinvention also provides for a variety of mechanisms to be associatedwith the ports 604. In the embodiment shown for example, a rotationmechanism 618 has a port 604 mounted thereon. Any number of rotationmechanisms 618 could be included on the surface of the support 602 suchas is shown. Alternatively a similar mechanism or mechanisms could beincluded on one or more surfaces of a module 606 to provide a dedicatedrotation module. The rotation mechanism 618 could also be configured asa gyrator or other motion producing device.

It must also be noted however that the three types module varieties 606a, 606 b and 606 c presently shown and described are merely threeexamples of potential module sizes and shapes. It should be understoodthat modules 606 may be configured in any size or shape as desired. Asindicated above, in order to ensure the greatest ease of use andelegance in design, it may be desirable to provide the various modules606 with uniform support members 610 and also provide the support 602with similarly uniform ports 604. However, in order to ensure that onlycertain module types are utilized in certain ports, it is recognizedthat the present invention could also utilize a support 602 having avariety of port 604 configurations with modules 606 having modulesupports 610 sized to correspond with specific ports and/or ports 604.

In keeping with the modular construction of the present invention, itshould also be understood that the support 602, like most of thecomponents thus described could be embodied in a variety of shapes andsizes. Preferably, the support 602 is a circuit board with a number ofports 604 included thereon. In one aspect of the invention, the support602 could be embodied as several supports with each support having aunique arrangement of modules and light sources. The electronicschematics shown in FIGS. 52-55 show some possible configurations andtheir associated electronic connections between the various componentsof the invention.

Starting in FIG. 52, an embodiment of the invention is showed where thecontroller 50 is in electronic communication with one or more supports602, which are in turn in electronic communication with one or moremodules 606, which are in turn in electronic communication with one ormore light sources 30. FIG. 53 shows a similar series of electricpathways, but in the present embodiment the controller 50 may also be indirect electric communication with each of the various components,support(s) 602, module(s) 606 and light source(s) 30, independent of oneanother.

In the embodiment shown in FIG. 54, the individual visible surfaces 612of the various modules 606 may be controlled by the controller 50.Though not indicated in the schematic, the various components: supports602, modules 606, visible surfaces 612 and light sources 30 may beindependently controlled by the controller 50 or may be selectivelyactivated via the electronic pathway shown.

In the embodiment shown in FIG. 55, a support 602 includes a controller50. Each controller 50 is in electronic communication with an externalcontroller 55 in the manner previously discussed above. The embodimentshown in FIG. 55 could include numerous independently controlledsupports 602 which are in communication with the external controller 55.It should also be noted that individual controllers 55 could also beincluded with each modules 606 to provide for a warning signal lighthaving numerous predetermined light signals or patterns which could bedisplayed by sending a single signal from the external controller 55 tothe various controllers 50.

In reference to the various embodiments shown in FIGS. 52-55, one ofordinary skill in the art will recognize that additional componentscould be added to any of the various embodiments shown and that numerousconfigurations other than those shown or described could be created. Thepresent invention is directed to all possible arrangements of thevarious components described herein regardless of the number, type orarrangement of the components described herein.

It should also be noted that the controller 50 and/or externalcontroller 55 described in relation to FIGS. 52-55 may provide modulatedand/or variable power to individual light sources 30 or modules 606 asearlier described. It should also be noted that the controller 50 orexternal controller 55 may selectively illuminate any combination ofindividual light sources 30 or modules 606 to provide an infinitevariety of patterns and/or combinations of patterns for a warning lightsignal independently of, or in combination with, the provision ofmodulated or variable power intensity as earlier described.

Turning to FIGS. 56-58, several views of an example of a module 606 isshown. Typically, a module will include a base portion 620 and lightmounting portion 622. The base portion 620 will include the supportmember 610 which will typically include a plurality of electric contacts608. The support member 610 and the electric contacts 608 are removablyengageable to a port 604 as previously described. The contacts 608provide the module 606 with an electric path to the support 602 andcontroller 50 such as is shown in FIGS. 51-55.

The light mounting portion 622 preferably is a vertically orientedcircuit board 630 which includes one or more light sources 30 andassociated culminator cups 370 with reflective surfaces 616 removablymounted thereon. The light sources are preferably LEDs. As shown in FIG.51 the light mounting portion 622 may be enclosed in a transparent coveror dome such as protector 290.

As depicted in FIGS. 61, 62, 65, and 66, an LED take-down light 700 andan LED alley light 702, 800, 808 are shown as being integral to a lightbar 704, 760 mounted to an emergency vehicle 706.

The LED take-down light 700 may be formed of one or more LED's 336 asearlier described. The LED's 336 forming the LED take-down light 700 mayeach be surrounded by a culminator 370 as depicted and described withreference to FIGS. 26-32 having one or more reflective sections 374 fortransmission of light along a desired line of illumination.Alternatively, a reflector 350, 434 may be positioned adjacent to LEDlight sources 336 as described in reference to FIGS. 37-47. Thereflector 350, 434 used in conjunction with take-down light 700 may bestationary or may be rotatable through the use of a rotational device atthe preference of an individual. The LED's 336 forming the LED take-downlight 700 may also be angularly offset with respect to horizontal toprovide illumination along a preferred line of illumination as earlierdescribed and depicted within FIGS. 13 and 14.

The LED take-down light 700 may be integral to, or mounted upon, thelight bar 704, 760 at the discretion of an individual. It should benoted that the LED take-down light 700 may be formed of panels ormodules of LED illumination sources as depicted and described in FIGS.31-32 and 51-58. The LED take-down light 700 may also include circuitboards as earlier depicted and described further using culminatorreflectors 370, within a frame or support assembly as earlier described.

The LED take-down light 700 preferably provides enhanced utility for anemergency vehicle warning signal light system for reduction of currentdraw requirements, electromagnetic emissions while simultaneouslyproviding increased useful life, and enhanced true light output colorfor an illumination source. The use of an LED take-down light 700incorporating LED technology improves illumination of areas in front ofan emergency vehicle by flooding the area occupied by a stopped vehiclewith light while simultaneously secreting the actions and location oflaw enforcement personnel during law enforcement activities. Theillumination of the LED take-down light 700 also assists in enhancingthe visibility of an emergency vehicle during dark illuminationconditions which in turn improves the safety for law enforcementpersonnel.

The LED take-down light 700 is preferably coupled to a power supply,battery, or other low voltage power source. The take-down light 700 mayalso be electrically coupled to a controller 50 for illumination of allor part of the LED light sources 336 to provide for a desired level ofillumination for an area adjacent to an emergency vehicle. Thecontroller 50 may alternatively provide a constant light effect, strobelight signal, pulsating light signal, flashing light signal, theillusion of rotation or oscillation for the light signal, or a modulatedlight signal or may include images or characters as earlier described.

Further, the intensity of the LED light sources 336 may be selectivelyregulated by a controller 50 dependent upon the darkness of theconditions to be illuminated during law enforcement activities. Thecontroller 50 may be coupled to a light or photosensitive detector toassist in the selection of a desired level of light output dependentupon the environmental conditions encountered by the law enforcementpersonnel during use of the LED take-down light 700.

The LED take-down light 700 may be formed of one or more adjacent panelsor modules 480 of LED illumination sources 336 along a front face 710,764 for a light bar 704, 760. Alternatively, a plurality of panels ormodules 480 of LED light sources 336 may be formed along the front face710, 764 of the light bar 704, 760 as well as a plurality of panels ormodules 480 of LED light sources 336 along the rear face 712, 776 of thelight bar 704, 760. It should be noted that the panels or modules 480selected for the LED illumination sources 336 may be linear, square,rectangular and/or may have two or more sides, or may be a singleillumination source at the discretion of an individual. Each individualpanel or module 480 of LED illumination sources 336 may be independentlyilluminated by a controller 50 to provide one of a plurality ofindividual and distinct warning light effects as earlier described. Forexample, a first, third, and fifth panel or modules 480 of LED sources336 may be illuminated where the second and fourth panels or modules 480are not illuminated. Alternatively, the first, third, and fifth panelsor modules 480 of LED light sources 336 may be continuously illuminatedand the second and fourth panels or modules 480 may be illuminated toprovide a flashing or strobe light signal. It should be noted thatillumination of any combination of panels or modules 480 may be providedas desired to create a preferred unique warning light signal for the LEDtake-down light 700. A constant illumination signal may be provided or aflashing, strobe, and/or modulated light intensity may occur to provideone of a plurality of distinct light signals as desired within anemergency situation.

It should be further noted that the LED light sources 336 within the LEDtake-down light 700 may be angularly offset as depicted within FIG. 14to provide a maximum illumination at a preferred distance adjacent tothe front of a law enforcement vehicle.

The LED take-down light 700 may be used within any desired type ofemergency vehicle including but not limited to automobiles, motorcycles,snowmobiles, personal watercraft, boats, trucks, fire vehicles,ambulances, and/or helicopters.

The LED take-down light 700 may be preferably releasably secured to thetop of an emergency vehicle or light bar 704, 760 through the use ofstandard affixation mechanisms including, but not limited to, the use ofsuction cups, hook and loop fasteners, brackets, screws, bolts, and/orother fasteners at the preference of an individual. It should be notedthat the LED take-down light 700 may be permanently secured to a lightbar 704, 760 or may be releasably attached thereto for separation anduse as a remote beacon as described in FIG. 15.

The take-down light 700 may alternatively be formed of strips of LEDlight sources 308 as previously disclosed with respect to FIG. 34.During use of strip LED light sources 308 a culminator/reflector 370 maybe used for positioning adjacent to each individual LED light source 336to reflect light along a desired line of illumination. The strip LEDlight sources 308 may preferably include adhesive backing material andtransparent protective covers to prevent contamination includingexposure to water which may adversely affect the performance of theindividual LED light sources 336. The adhesive backing material may beused to permanently or releasably secure the strips of LED light sources308 in a desired location within the LED take-down light 700.Alternatively, the take-down light 700 may be integral to light barspreviously illustrated and described.

As depicted in FIGS. 61, 62, 65, and 66, the LED alley lights 800, 808provide illumination perpendicularly outward from a vehicle illuminatingareas adjacent to the drivers side and passengers side of the vehicle706. The LED Alley lights 800, 808 are almost identical in constructionand functionality to the LED take-down light 700. The LED alley lights800, 808 may be mounted to a mechanical pivot, gears, and/or rotationaldevice which may include an electric motor. The rotation of themechanical pivot, or gears may alternatively be terminated to permitfixed angular illumination of areas adjacent to a law enforcementvehicle 706 which are not perpendicular to either the drivers orpassenger sides in a manner similar to the functionality and operationof a spot light. In this regard, the LED alley lights 800, 808 may bemanipulated forwardly, rearwardly, upwardly, and/or downwardly toprovide illumination of a desired area relative to an emergency vehicle706. The LED alley lights 800, 808 may be integral to, or removablefrom, the light bar 704, 760. As such, the LED alley lights 800, 808 maybe releasably secured to the ends of the light bar 760 through the useof fasteners 778 such as bolts and nuts, screws, adhesives, straps,and/or hook and loop fabric material at the preference of an individual.It should be noted that an individual may simultaneously illuminate theLED take-down light 700 and the LED alley lights 800, 808 or mayalternatively illuminate the LED alley lights 800, 808 independentlyfrom the LED take-down light 700 as desirable within an emergencysituation.

Referring to FIGS. 61, 62, 65, and 66, the take-down light 700 may bepositioned inside of a housing, base, or enclosure 780 which preferablyhas a transparent surface 782 permitting light as emitted from LED lightsources 784 to pass therethrough. Within the interior of thebase/housing 780 are preferably located one or more light emitting diodelight sources 784. Each LED light source 784 may include one or moreindividual light emitting diodes 786 as integral to circuit board 788.The functions and operation of LED light sources, LED's, and circuitboards are earlier described with reference to FIGS. 31 and 32 herein.Each LED light source 784 may also include electrical couplers orconnectors 790 which may be adapted for penetrating engagement into areceiving slot 792. The LED light sources 784 may be modular as earlierdescribed with reference to FIGS. 51-58 to facilitate ease ofreplacement herein. An individual may thereby easily replace and/orsubstitute an LED light source 784 with another light source having thesame or different colors or intensity characteristics as desired by anindividual. It should be noted that the circuit board 788 and/or LEDlight sources 784 may be panels or strips as described with reference toFIGS. 34 and 35.

The circuit board 788 may additionally include heat sink wells 344 asdescribed with reference to FIG. 36. The LED light sources 784 may beeither removably or fixedly secured to the housing/enclosure 780 at thepreference of an individual. It is therefore apparent that alternativecolors may easily replace current LED's 786 and/or replacement LEDmodules by insertion into and/or removal from a corresponding receivingslot 792.

The LED lights 786 are preferably spaced about circuit board 788 in anydesired pattern and/or combination including the use of a linearconfiguration. Adjacent to each LED light source 784 is preferablypositioned a reflector which may be a culminator 730, 534, as earlierdescribed in reference to FIGS. 26-32 and 47. Alternatively, a reflectoror mirror 802, 434, 350, as described in reference to FIGS. 21, 22,37-39, 40-42, and 47, may positioned adjacent to LED light sources 784to reflect light emitted by LED's 786 in a desired direction formaximization of illumination characteristics for the alley lights 800,808 and/or take-down light 700. The utility of the alley lights 800, 808and/or take-down light 700 is thereby enhanced. The reflectors 370, 534,434, 802, or 350 may be integral and/or attached to circuit board 788 orto a frame or support adjacent to circuit board 788 to reflect lightemitted from LED's 786 along a desired line of illumination. Thereflector/culminators 370, 534, 434, 802, or 350 may be secured in adesired location through the use of adhesives and/or mechanical devices.

Within the housing/enclosure 780 is preferably located a motor 794having a worm gear 796 engaged to a shaft 798. Engagement of motor 794rotates shaft 798 in turn rotating worm gear 796. The motor 794 ispreferably electrically coupled to the electrical system and/orcontroller 50 for the emergency vehicle.

A first alley light 800 may be positioned within housing 780 proximateto motor 794. The first alley light 800 may be stationary and/orrotatable relative to the light bar 760 at the preference of anindividual. The first alley light 800 is preferably adapted to flood theenvironment perpendicular to the sides of a vehicle with light, such asdown and “alley”, by a passing emergency or law enforcement vehicle. Thefirst alley light 800 is preferably formed of one or more LED's 786which are preferably each positioned within a culminator reflector 802for reflection and maximization of light transmission along a desiredpath of illumination. The first alley light 800 may or may not beengaged to a gear 804. If rotation of the first alley light 800 isdesired, then gear 804 may include a receiving slot 792 to provideelectrical connection and power to the LED light source 784 forprovision of light. Gear 804 may also be coupled to worm gear 796 forthe provision of rotation and/or oscillation motion. If motion of firstalley light 800 is not desired, then stationary positioning of LED lightsources 784 relative to housing 780 may be provided with suitableelectrical connection to a vehicle power source. Take-down light 700,first alley light 800, second alley light 808 may be alteratively formedin any shape as earlier described in reference to FIGS. 4-10, 12, 23-25,31, 32, 34, 35, 37-39, 51, and 56-58. Take-down light 700, first alleylight 800, and second alley light 808 may be stationary within housing780.

A second gear 806 may be provided for central positioning within housing780. The second gear 806 may preferably be coupled to gear 804 which mayin turn be coupled to worm gear 796 as connected to shaft 798. Rotationof shaft 798 by motor 794 thereby imparts rotation of gear 804 andsecond gear 806. Alternatively, the shaft 798 may be elongate includingworm gear 796 for direct coupling to second gear 806. Rotation of 360°or oscillating rotation of second gear 806 may therefore be provided.

Second gear 806 may also include a receiving slot 792 adapted toreceivingly engage electronical connectors 790 as integral to circuitboard 788 of LED light sources 784. Light sources 784 also preferablyinclude a plurality of individual LEDs 786 which may each be positionedwithin a culminator 534, 370, 802 as earlier described. A controller 50as earlier described may be electrically connected to each LED lightsources 784 as coupled to either gear 804, second gear 806, third gear810, and/or housing 780 for selectively illumination of individual LED's786, or for illumination of a combination of LED's 786 as desired. Itshould be noted that the features as earlier described for controller 50are equally applicable for use with the take-down light 700, first alleylight 800, and second alley light 808, relative to distinct types andcombinations of types of warning light signals including the use ofmodulated and/or variable light or power intensity for the creation of adesired unique or combination warning light effect.

Second gear 806 may be further coupled to third gear 810 which mayinclude a receiving slot 792 adapted for electrical coupling toconnector 790 of take-down light 700.

Second alley light 808 is preferably designed to be rotated and to sweepforwardly to the front of an emergency vehicle at such times when theintersection clearing light mode has been activated. During activationof the intersection clearing light mode, the take-down light 700 aselectrically coupled or integral to third gear 810 will rotate sweepingto the outside corner of an emergency vehicle.

The controller 50 is preferably in electrical communication with thetake-down light 700, the first alley light 800, and the second alleylight 808. Any number of take-down lights 700 or alley lights 800, 808may be used in association with a light bar 704, 760. The controller 50additionally regulate the rotation of the motor 794 for impartingrotation to the take-down light 700, and/or the alley lights 800 and808.

The controller 50 activating the motor 794 may selectively initiate anintersection clearing illumination mode or sequence. Motor 794 causesthe shaft 798 to rotate imparting motion to the worm gear 796. Therotation of the worm gear 796 may be transferred to the first alleylight 800 through the coupling to the first gear 804. Alternatively, theworm gear 796 may be directly coupled to the second gear 806. In anotherembodiment, motion may be imparted to the second gear 806 through theuse of a tie bar 842 as connected between the second gear 806 and thefirst gear 804. Rotation of the worm gear 796 rotates first gear 804whereupon motion may be transferred to the second gear 806 for movementof the second alley light 808. Rotation may be further transferred tothe take-down light 700 via the coupling of the third gear 810 to thesecond gear 806. The tie bar 824 may extend between gear 804 and secondgear 806 to synchronize motion, rotation, and illumination of the firstalley light 800 relative to the second alley light 808 and take-downlight 700.

Each of the first alley light 800, second alley light 808, and take-downlight 700, are preferably in electrical communication with a powersource for a vehicle and are further in communication with thecontroller 50. The controller 50 may independently impart motion to thetake-down light 700, first alley light 800, and second alley light 808.The alley lights 800, 808, and take-down light 700 may be selectivelyilluminated without initiation of rotational motion as regulated by thecontroller 50. Alternatively, the controller 50 may signal engagement ofthe motor 794 to impart rotation to any one of the first alley light800, second alley light 808, and/or take-down light 700 for use as anintersection clearing light. The controller 50 is therefore capable ofsimultaneously regulating motion of the rotational devices such as gears804, 806, and 810 and illumination of selected individual or groups ofLED's 786 to provide independent or combination light effects.

The intersection clearing light mode may generally be initiated by thecontroller 50 which signals motor 794 to rotate second gear 806 eitherthrough rotation of first gear 804 or through direct contact with wormgear 796. The first or at rest position for the second alley light 808preferably directs the transmission of light in the direction depictedby arrow 812 which is generally perpendicular to the longitudinal axisof a vehicle. As the intersection clearing light mode is engaged, thecounter clockwise rotation of gear 804 causes the clockwise forwardrotation of the second gear 806 according to arrow 814 until an angle offorward rotation 816 is achieved. The direction of forward rotation 816preferably transmits light emitted from LED light sources 784 forwardlytowards a corner of a vehicle at an approximate angle ∝ of 45°. Thecontroller 50 may then continue to rotate the gears 804, or 806, in acounter clockwise direction for 360° rotation, or alternatively thecontroller 50 may signal the motor 794 to reverse direction to rotatethe second alley light 808 rearwardly back to the first at rest positionindicated by number 812. During the clockwise rotation the second gear806, third gear 810 and take-down light 700 may be rotated in a counterclockwise direction. The initial at rest position for the take-downlight 700 is forwardly with respect to the alley lights 800, 808. Theengagement of the intersection clearing light mode rotates the take-downlight 700 outwardly towards the sides of an emergency vehicle from afirst position indicated at 818 to a second position indicated at 820 asdepicted by arrow 822.

Alternatively, the first alley light 800 may be rotated simultaneouslywith the second alley light 808 by engagement between the first gear 804and second gear 706. Synchronous rotation between the first alley light800 and the second alley light 806 may be provided through the use ofthe tie bar 824 or through direct coupling engagement of gears 804 and806.

In an alternative embodiment as depicted in FIG. 66, the first gear 804is not required to be connected to the second gear 806 with theexception of the tie bar 824. The tie bar 824 preferably extends betweenthe first gear 804 and the second gear 806 and is pivotally androtatably engaged to each of the first and second gears 804, 806respectively. The initial positioning of the tie bar 824 on the firstgear 804 may be initially indicated as the at 0° location. The initialposition of the tie bar 824 on the second gear 806 may also be initiallyindicated as the at 0° location where the tie bar 824 extends in alinear direction between the first and second gears 804, 806 proximateto the circumference of each of the first and second gears 804, 806respectively.

The second alley light 808 is initially positioned for transmission oflight outwardly from the housing 780 opposite to the location of the tiebar 824. The second alley light 808 is preferably positioned for lighttransmission at a location approximately 180° from the tie bar 824 onthe second gear 806.

As the motor 794 is engaged, the first gear 804 may be rotated in eithera clockwise or counter clockwise direction relative to the housing 780.A clockwise rotation or the first gear 804 will be described herein fortransfer of motion to the second gear 806 and third gear 810.Alternatively, the motor 794 may be configured to rotate the first gear804 in a clockwise direction for a desired period of time or distance,and then reverse directions for counterclockwise rotation of the secondgear 806 for a desired period of time or distance. It should also benoted that in an oscillating sequence the first gear 804 may beinitially rotated 90° in a clockwise direction or counter clockwisedirection and then the direction of rotation may be reversed forrotation of 90° or 180°, whereupon rotation may again be reversed forcontinued rotation of either 90° or 180° in the initial direction.

In a 360° rotation cycle of the first gear 804 in a clockwise direction,motion is transferred to the second gear 806 and third gear 810 in apush-pull configuration through the tie bar 824. Clockwise rotation ofthe first gear 804 from a position of 0° to a position of approximately90° causes the second gear 806 to be pulled by the tie bar 824 movingthe position of the second alley light 808 from an initial position of180° to a position of approximately 270°. Continued rotation of thefirst gear 804 from a position at 90° to a 180° location preferablycauses the second gear 806 to be pushed by the tie bar 824 causing thesecond alley light 808 to be rotated in a reverse, direction from a 270°position back to a 180° position. Continued rotation of the first gear804 in a clockwise direction from a position 180° to a 270° location inturn causes the tie bar 824 to pull the second gear 806 causing thesecond alley light 808 to continue to be rotated in a reverse directionfrom a position of 180° to a 90° location. Continued rotation of thefirst gear 804 in a clockwise direction from a 270° position to a 360°or initial position in turn causes the tie bar 824 to push the secondgear 806 causing the second alley light 808 to reverse directions to berotated from a 90° position to an initial or starting position of 180°.

Rotational motion is also, in turn, transferred to the third gear 810due to the coupling engagement with the second gear 806. The rotationalmotion of the third gear 810 relative to the second gear 806 is in theopposite direction. The initial positioning of the take-down light 700on the third gear 810 is preferably offset relative to the second alleylight 808. The initial positioning of the second alley light 808 may beindicated as 180° and the initial position of the take-down light 700may be initially indicated as 270°. The third gear 810 and the take-downlight 700 are, therefore, preferably initially rotated from 270° in acounter clockwise direction to approximately 180°. The rotation of thethird gear 810 and the take-down light 700 is then reversed from 180°back to 270° and then to 360° where rotation may be reversed back to270° at the preference of an individual. The take-down light 700therefore wags and oscillates between 360° or 0° to 180° through aninitial positioning of 270°. Simultaneously, the second alley light 808is wagged or oscillated between 90° and 270° through an initial positionof approximately 180°.

The offset positioning of the second alley light 808 relative to thetake-down light 700 prevents obstructed contact between the two lightsources 784 permitting free rotational motion therebetween. The offsetpositioning of the second alley light 808 relative to the take-downlight 700 enables the utilization of oversized or enlarged LED lightsources 784 as engaged to the second or third gears 806, 810respectively. The illumination as transmitted by the LED light sources784 may thereby be significantly increased for unobstructed rotationbetween the second and third gears 806, 810.

Alternatively, the rotation of the second gear 806 and third gear 810may occur through an arc of approximately 360°. It should be noted thatthe controller 50 is not required to continuously illuminate either thetake-down light 700, first alley light 800, and/or second alley light808 where the area of illumination will not be visible to an individualrelative to a vehicle. Alternatively, the first gear 806, and third gear810 may be rotated to a desired position such as indicated by thenumbers 820, 816, and oscillated for return to an initial position 818,812, at the discretion of an individual. The controller 50 may regulatethe rotation of the gear 804, second gear 806, and third gear 810, forillumination of LED's 786 during use as an intersection clearing light.The intersection clearing light, take-down light, and/or alley lights,are preferably positioned inside the housing 780 located at the distalends of LED light bar 760 as depicted in FIG. 63. The intersectionclearing light, take-down light, and/or alley lights preferably provideillumination to the sides and further preferably provide illuminationangularly with respect to the sides of a vehicle.

The intersection clearing lights, take-down lights, and/or alley lightsmay additionally include a switch for regulation of rotation of thetake-down lights 700 and alley lights 800 or 808, to a desired anglewhere upon rotation may be terminated. In this situation, the take-downlights 700, and/or alley lights 800, 808, may be utilized in a mannersimilar to a spotlight integral to a vehicle and as controlled by anoperator. The controller 50 or switch may be utilized to provide anydesired angle of illumination for the take-down light 700 within an arcof approximately 180° relative to the front and sides of a vehiclebetween an angle of approximately 45° forwardly and inwardly to anapproximate angle of 135° rearwardly and outwardly with respect to thefront and sides of a vehicle. The controller 50 or switch may also beutilized to provide any desired angle of illumination for the alleylights 800, 808, within an arc of approximately 140° relative to thesides of a vehicle between an angle of approximately 70° forwardly andoutwardly to an approximate angle of 70° rearwardly and outwardly fromthe sides of an emergency vehicle. A wide area of illumination to thefront and sides of an emergency vehicle is thereby provided by the alleylights 800, 808, and take-down light 700 either independently and/or incombination. The controller 50 may independently illuminate either thealley lights 800, 808, and/or take-down lights 700 as desired by anindividual.
